Shock

Mario Bava's final film proved that his one true strength was surreal, nightmarish imagery (when that kid runs up to Daria Nicolodi...), and though I've found most of his body of work to be overrated and dull, I was able to tolerate, even enjoy "Shock" (though it does become talky and drawn-out); the presence of Nicolodi ("Deep Red," "Tenebre") as a mentally unbalanced mother adjusting to her family's new (and haunted) house, offers up enough paranoia and sex appeal to make the final act as suspenseful as the workings of a bad dream. Shades of this film can also be seen in Lucio Fulci's "House by the Cemetery" (another good exercise in Italian horror).
